Night vision camera selection: In addition to see the minimum illumination also pay attention to what?

As the basis of video surveillance, cameras occupy a pivotal position in the entire security field. With the development of the security industry, the transmission mode of the camera has evolved from an analog network to a digital network; the clarity of the display has ranged from SD to HD to full HD, and even 4K and 8K ultra-high-definition has emerged; the low-light level is also from the moonlight. From grade to starlight level to super starlight, until now the black light or can be called the night full color vision, the progress of camera technology can be described as ever-changing. With the advancement of technology, the camera's image transmission, clarity, low illumination and other performance are also constantly improving. The problem with the current frame-accumulating cameras is black and white picture quality in the evening, delayed smearing, and discontinuous pictures. Although the traditional infrared light-filling technology can obtain clear imaging under low illumination, it also loses color and can only form black-and-white images. Infrared light supplement also has short irradiation distance, attenuation effect, uneven light, and high heat generation. Problems such as short service life, license plates and other highly reflective objects are also easy to over-exposure, and clothing colors, body colors, license plates, etc. are often the key clues to solve the case, and can not be lost, so the clear color imaging needs under low illumination more The more you come. Cameras must not only be monitored 24 hours a day, but also have more and more complicated applications. The application and manufacturing of low-light cameras have become more and more mature, and most manufacturers have developed the camera illumination lower and lower, roughly from 1.0Lux to now marked 0.0001Lux.
